Free-Hanging Rescue

If you can't reach the tree, you must secure the rescue rope to the glider itself:
Open the rescue bag and pull out the long sling, which should already be tied in a loop. Thread one end of the loop through all the quick links connected to your lines (both risers). Pass the other end of the loop through the threaded end, creating a girth hitch. Pull the hitch tight, cinching all your lines into a tight bundle.
Put one foot in the long sling like a stirrup and push hard enough to keep the lines bundled together. (It's important that the sling be long enough that you can use it as a stirrup. Fifteen feet tied in a loop is long enough for a six-foot-plus pilot.)
Locate the two short slings and locking carabiner. Girth hitch a short sling to each riser carabiner. Then clip the slings together with the locking carabiner.
Thread the loop at the free end of your rescue rope through the same quick links the long sling has been threaded through. Pass the stuff bag through the loop, creating a girth hitch. Cinch it tight. Drop the stuff bag to the ground.
Wrap the rescue rope around the locking carabiner that you clipped to the two short slings (as illustrated above). Lock the carabiner.
Now snug up the rappel rope so there is no slack between the rappel carabiner and the anchor point. Take the free end of the rappel rope and wrap it several times around your thigh on the leg that's not in the stirrup. This ensures that the rappel rope won't slip during the following critical steps.
Stand up in the stirrup, unweighting your risers. One side at a time, unclip your risers from your harness, taking care not to unclip the short slings that you girth hitched to your harness carabiners.
Slowly lower yourself in the stirrup until your weight comes onto the rappel carabiner. Make sure that the carabiner is straight and neatly wrapped. Remove your foot from the stirrup.
Keeping hold of the rappel line, unwrap the line from your other leg. Lower yourself slowly to the ground.
